I swear it runs smoother and quieter. Which given the low mileage on the car and the oil almost certainly means it's a placebo effect I invented to justify the trouble I went to in order to source full synthetic, low NOACK, low SAPS oil and have the dealer pour it in for me.
Sounds like a nice dealership to do BYO oil for $21. I mean, after the filter, they are just getting a few bucks, that is a pretty good deal.
It might not be placebo effect. Many people report an engine preferring a specific oil, or if not preferring, sounding slightly different. I know one thing, you chose one of the very best 5w-30 available! Enjoy your car!
